Possible crown rot

So I bought a new orchid, the top most leaf was very lime green when I bought it and I figured it was just receiving too much light where ever it came from, but the leaf turned all the way yellow, but is still firmly attached to the plant.. however the odd thing is that the leaf directly below it it which was a very healthy green and firm, competely came off the leaf in a clean way when I touched it, so now It's going to loose 2 leaves, and has 3 remaining healthy leaves.. (there are 2 more, but they are small and covered by the larger leaves above them)..

The plant is in bloom, there has been no negative effect on the blooms or the plant as a whole yet.. the blooms keep opening and all look very healthy.. the stem is very healthy.. however I'm wondering if I should cut the spike and let the plant switch over to growing a new leaf quicker because I don't want to loose this plant. Would that be a good choice, or can the plant endure loosing the top 2 leaves while in bloom?

Thanks for responses

It's a Phal

Well, it depends on how much of the top leaf broke off. If the growing node came off with the leaf, the plant might not be able to grow from the crown. I had a phal that lost its top leaf, and it is sending up a terminal spike now.

In any case, I would enjoy those blooms and just see what your plant does.

Hi Emma, what's a terminal spike?

Thanks!

Oh, sorry. It's a spike that grows out of the top of the crown of the plant rather than from above one of the lower leaves. The word "terminal" does not mean fatal in this case, though. It just means the plant can't grow from the crown anymore.

I'm hoping my plant will throw a keiki, but it's a phal noid so if it doesn't, oh well.

one of my phals has the exact same issue as mentioned above (lost the top couple leaves) and it looks like the growth point had a fungal infection and appears to be shot. I didnt realize it when it was purchased or i probably would have picked a different plant. Anyway, treated the crown with cinnamon to stop further spread of rot and am watering carefully to keep crown dry. Can i save this plant? Mine too has flowers (3 spikes) that are still blooming normally. Half the roots turned out to be bad, but it still has enough healthy ones i think. Is there hope with the growth node gone?

As I said above, the plant may produce a terminal spike from the crown if it can't grow new leaves from there (if the growth node is gone). However, it might surprise you with a basal growth or a keiki.

My plant has plenty of roots, so I'm hoping it will grow one or the other, but we'll see. I guess we all have to wait and watch.
